APPENDIX A
USING THE RAIN HOOD (WEATHER-PROTECT-
ED LOUDSPEAKERS)
If your MILO 120 loudspeaker was ordered with optional
weather protection, a rain hood is installed on the MILO
120 loudspeaker. It is provided to protect the loudspeaker’s
electronics from direct exposure to rainfall. Before using the
MILO 120 loudspeaker, open the rain hood as described in
the following procedure.
1. Pull the exterior Velcro straps off the hood to allow it to
open.
2. Lift the flap fully outward, and unfold the fabric of the
rain hood.
3. With your other hand, reach into the hood and free the
two PVC supports from their corner pockets in the outer
flap.
4. Fold both supports out and re-insert them into the two
pockets, shown in Figure A.1, in the lower corners of
the soft side flaps. This will hold the rain hood fully open
for use, which is necessary for proper cooling of the
MILO 120 loudspeaker’s electronics.

CAUTION: When operating a weather-pro-
tected MILO 120 loudspeaker be sure the rain
hood is fully open. Leaving the hood closed or par-
tially open will limit the air.ow through the amplifier,
which could cause it to overheat and shut down.
REMOVING THE HP-4/MILO 120 AMPLIFIER
CAUTION: Please note that MILO 120 and
MILO amplifiers are different. Specific func-
tions for each model, such as crossover points, fre-
quency and phase correction and driver protection
are determined by the control cards installed inside
the amplifier. Do not exchange amplifiers between
MILO and MILO 120 loudspeakers.
If you need to remove the HP-4/MILO 120 amplifier from a
loudspeaker, perform the following steps:
1. Using a #2 Phillips screwdriver, remove all eight screws
from the amplifier module. This will free the HP-4/MILO
120 electronics module from the cabinet (Figure A.3).

amplifier module
2. Carefully slide the amplifier module out of the cabinet
using care not to stress the cables.
3. Disconnect the two 4-pin loudspeaker connectors. Note
that the harness with red and black wires goes to the
connector closest to the user panel, while the harness
with green and white cables goes to the connector
closest to the fans (Figure A.4).
